What is a Surgical Anesthesia System?

1. The main function of the surgical anesthesia system

The surgical anesthesia system can better and more accurately record and manage the clinical information of surgery and anesthesia, and improve the work efficiency of doctors and anesthesiologists. It is mainly used for the application, approval and arrangement of patients' surgery and anesthesia, accurately records the patient's medical orders during the operation, intraoperative expenses and other information, and tracks vital signs and other monitoring data, such as heart rate, blood pressure, blood oxygen saturation information , and the entry of postoperative doctor's orders. The arrangement of hospital operation and anesthesia is a complicated process, and the operation anesthesia system can effectively ensure that the hospital operation is carried out reasonably, effectively and safely.

2. Departments involved in surgical anesthesia


1. The department where the patient is located: before the operation, the doctor will issue an operation application and provide the operating doctor.
2. Chief surgeon's department: The patient's chief surgeon may not necessarily be the patient's attending doctor, but may be a doctor called from other departments.
3. Pharmacy department: provide medicines needed for surgical anesthesia. (Some hospitals have operating room pharmacies, and surgical medicines and health materials are directly provided by the operating room pharmacies).
4. Hygienic material department: provide hygienic materials required for surgical anesthesia.
5. Blood Bank: Provide blood needed by surgical patients.
6. Inspection department: The inspection and inspection report of the patient can be extracted during the operation.
7. Operating room: provide the place for the operation and the nurses who perform the operation, arrange to prepare the operation room, and some hospital operation nurses are arranged from the clinical department.
8. Department of Anesthesiology: mainly responsible for preoperative visits, anesthesia for patients during surgery, preparation and treatment before and after anesthesia, patient monitoring and treatment, first aid recovery, pain treatment, etc.
9. Anesthesia recovery room: The anesthesia recovery room is one of the important components of the anesthesiology department, and its main task is to ensure the safety of patients during the anesthesia recovery period. The recovery period of general anesthesia has the same risks as the induction period, and patients may experience changes in breathing, circulation, nervous system, metabolism, etc. at any time during this period. In order to enable patients to go through the operation period more safely and effectively, prevent postoperative complications, and achieve the goal of early and comprehensive recovery, it is necessary to implement routine post-anesthesia monitoring for all patients undergoing general anesthesia and regional anesthesia.
10. Nursing department: do a good job of patient handover records and postoperative signs records (see the specific regulations of the hospital).
11. Toll room: collect the operation fee of the operation patient.


3. Personnel and work content involved in surgical anesthesia


1. Chief surgeon: The chief surgeon is the doctor who is mainly responsible for performing the operation.

A. Formulate the operation plan
B. Issue the operation application form
C. Perform the operation
D. Postoperative visit

Postoperative visits to understand the recovery situation, provide professional advice, and guide postoperative rehabilitation.

3. Anesthesiologist: The anesthesiologist should treat the medical problems of the patient during the perioperative period (during the operation, before and after the operation).

The anesthesiologist judges the condition before the operation, considers individual differences according to the patient's physical condition, and formulates a treatment plan based on this, and uses advanced instruments to monitor the patient's vital functions during the operation.

Contents of preoperative visit: Before anesthesia, patients should be visited before operation, including reading medical records, understanding the overall situation of the patient, emphasizing on previous operation history, anesthesia history and preoperative preparation, and making necessary examinations. At the same time, understand the patient's concerns, opinions and requirements about the operation and anesthesia, and make necessary explanations. At the same time, the possible risks and complications of anesthesia should be explained to the patient's family. According to the degree of cooperation of the patient and the method of operation, appropriate anesthesia drugs and methods are selected, and supplementary opinions on preoperative preparations are provided when necessary.

5. Hand washing nurse: directly participate in the operation and cooperate with the doctor to complete the whole process of the operation. Its scope of work is limited to the sterile area, such as transferring instruments, materials and various objects. Because they work in a sterile area, they must wash their hands and arms, wear sterile surgical gowns and sterile gloves, so they are also called hand washing nurses, sterilization nurses or surgical nurses.

E. After the operation, clean the general instruments and fine instruments, dry them and put them back to their original places.
F. There is no substitution during the whole operation.
 

6. Itinerant nurses: Although they do not directly participate in the cooperation of surgical operations, they are assigned in a fixed operating room to cooperate with hand-washing nurses, operators, assistants and anesthesiologists to complete surgical tasks. The scope of indirect cooperation is outside the sterile area, among patients, surgical personnel, anesthesiologists and other personnel, so it is called itinerant nurse.

J. Recording of events in the resuscitation room and rescue medical records;
Note: There is no strict division of labor between chief surgeon and assistant doctor, chief anesthetist and auxiliary anesthetist, which mainly depends on the specific regulations of the hospital. If there is no assistant doctor during the operation, all the work of the assistant doctor will be done by the chief surgeon. If there is no assistant anesthetist during the operation, the main anesthetist will also do the job of the assistant anesthetist.


4. The relationship between the characters in the operation


In an operation, the surgeon, anesthesiologist, and surgical nurse are all in a relationship of mutual assistance and cooperation.

Surgeon's order for surgery

The surgical nurse arranges the operation according to the operation doctor's order

The anesthesiologist conducts a pre-visit to the patient according to the surgical doctor's order, and feeds back the results of the visit to the surgeon

In the operation, the three parties must fully cooperate in order to successfully perform the operation. The anesthesiologist is the prerequisite for a successful operation, the surgeon is the key to a successful operation, and the surgical nurse is the guarantee for a successful operation.

Surgeons treat diseases, and anesthesiologists protect lives. Anesthesia and surgery are actually twin brothers, and neither will work without the other. The general process of preparing for anesthesia includes anesthesia machines, monitors, drugs, liquids, and then the establishment of pathways. Two pathways are very important to us. One is intravenous access, and the other is endotracheal intubation. We need to ensure the patient’s oxygen balance. It can regulate the patient's life indicators, his depth of anesthesia, consciousness, blood pressure, respiration, pulse, body temperature, acid-base balance, and a series of processes of electrolytes. The operation and anesthesia need to cooperate closely. How long the operation lasts depends on how long the anesthesia should be maintained. For a long time, first of all, the anesthesia has to be anesthetized before the operation is completed. After the second operation, it is not allowed to stay awake for a long time. Therefore, the surgeon should closely cooperate with the anesthesiologist on the operation time and operation steps, and the anesthesiologist should decide the drugs according to the operation steps.

5. Documents involved in surgical anesthesia

1. Operation application form: The operation notice is a written notice issued by the surgeon in the operation department for the operation patient. Within a limited time, (usually one day in advance) sent to the operating room for preoperative preparation. The operation notice is the link between the operation department and the operating room, and all work in the operating room is based on the operation notice.
It is a guide for the preparation of preoperative surgical supplies.

The drugs act on the spinal nerve roots, temporarily block the conduction of the spinal nerves, and cause anesthesia in the corresponding areas innervated by it, which is called intraspinal anesthesia. Neuraxial anesthesia includes subarachnoid block and epidural space.
Nerve block anesthesia: A local anesthetic is injected near a peripheral nerve trunk to anesthetize the area innervated by the nerve by blocking the conduction of nerve impulses.
Controlled hypotension: refers to artificially lowering the mean arterial pressure to a certain level during surgery under general anesthesia while ensuring the oxygen supply to vital organs, so that the blood loss in the surgical field decreases in parallel with the decrease in blood pressure, and makes the The surgical field is clear, reducing accidental injury to nerves and blood vessels, facilitating surgical operations, improving surgical accuracy, and shortening surgical time.
